Description

Technical Field

[0001] The utility model relates to the field of mask processing, in particular to a calendering device for mask processing. Background Art

[0002] A mask is a sanitary product, generally refers to a device worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. It is made of gauze or paper. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask is very effective when working in an environment polluted by dust. Masks can be divided into air-filtering masks and air-supplied masks.

[0003] The Chinese patent with publication number CN214056542U discloses a calendering device for mask production, including a calendering mechanism and a driving mechanism. The calendering mechanism includes a bottom plate, a universal wheel with a lock, a side plate, a lifting frame, and a sliding sleeve. Two side plates are welded on the top of the bottom plate, the universal wheel with a lock is installed at the bottom of the bottom plate, the lifting frame is slidably connected between the side plates, a threaded rod is fixed at the bottom end of the lifting frame, a threaded sleeve is connected to the outside of the threaded rod through a thread, the bottom of the threaded sleeve is rotatably connected to the bottom plate, a sliding rod is fixed at the bottom of the lifting frame and located on both sides of the threaded sleeve, and the sliding sleeve is slidably connected to the outside of the sliding rod. The utility model adopts a threaded rod and a threaded sleeve, so that the lifting bracket can be driven to rise and fall, and then the spacing between the two rollers can be adjusted, so that masks of different thicknesses can be adapted for calendering.

[0004] In actual use, debris will fall during the calendering process of the mask, and the screw and slide rod are set at the bottom, which is very troublesome for the later maintenance and cleaning of the device, and the debris may stick to the surface of the calendering roller, affecting the subsequent calendered masks.

[0027] Embodiment 1

[0028] See also Figures 1 to 4 The utility model provides a technical solution: it includes a fixed frame 1 and a base 8, a first calendering roller 5 and a second calendering roller 6 are symmetrically arranged inside the fixed frame 1, and movable grooves 11 are opened on both sides of the fixed frame 1, and lifting mechanisms 4 are arranged at both ends of the two first calendering rollers 5 and the second calendering rollers 6, a driving mechanism 2 is connected to one side of the first calendering roller 5, and a dust removal mechanism 3 is arranged on the upper end of the fixed frame 1.

[0029] The driving mechanism 2 includes a first rotating shaft 23 and a second rotating shaft 25 installed at one end of the two first calendering rollers 5. The first rotating shaft 23 and the second rotating shaft 25 are connected to each other through a second transmission belt 24. A first transmission belt 22 is provided on the side of the first rotating shaft 23 away from the second transmission belt 24. An elastic member 27 is provided inside the first transmission belt 22. A motor 21 is provided on the side of the first transmission belt 22 away from the first rotating shaft 23. A winding roller 7 is connected to the output end of the motor 21. The end of the winding roller 7 close to the motor 21 is connected to the first rotating shaft 23 through the first transmission belt 22. A stabilizing block 26 is sleeved on the side of the first rotating shaft 23 and the second rotating shaft 25 away from the first transmission belt 22. The lower end of the stabilizing block 26 is fixedly connected to the top of the lifting mechanism 4.

[0030] The lifting mechanism 4 is arranged in two groups of movable grooves 11 symmetrically opened on the fixing frame 1. The lifting mechanism 4 includes a fixing buckle 41 fixed to the stabilizing block 26. A hydraulic lifting rod 42 is arranged at the lower end of the fixing buckle 41. The fixing buckle 41 is provided with an upward opening.

[0031] The utility model sets a driving mechanism 2 on the outer side of the fixed frame 1 to ensure that the calendering roller can rotate and calender normally. The two sets of calendering rollers enable the material to be calendered twice, thereby improving the calendering effect of the material. A lifting mechanism 4 is set at both ends of the first calendering roller 5 to lift and lower the calendering roller at the upper end, thereby adjusting the distance between the calendering rollers. When the calendering roller is raised, the elastic member 27 in the first crawler 22 at the rear end contracts, so that the length of the first crawler 22 can be lengthened, thereby preventing the first crawler from being broken. During use, due to the fixation and limitation of the movable groove 11, the calendering roller can be lifted and lowered more stably, and will not block part of the base 8, making it more convenient for workers to clean up later, thereby improving the practicality of the device. The two crawlers set outside the fixed frame 1 will drive the two first calendering rollers 5 while also rotating the winding roller 7, making the device more convenient to use.

[0032] Embodiment 2

[0033] On the basis of embodiment one, the dust removal mechanism 3 includes a collecting box 31 fixed to the upper end of the fixed frame 1, an exhaust fan 32 is provided on the side of the collecting box 31 away from the driving mechanism 2, a transmission pipe 33 is fixed on one side of the exhaust fan 32, the lower end of the transmission pipe 33 is connected to the fixed frame 1, a through hole matching the transmission pipe 33 is provided on the side of the fixed frame 1 close to the transmission pipe 33, an opening for the transmission pipe 33 to pass through is provided on the side of the collecting box 31 close to the exhaust fan 32, and an extraction box is provided in the collecting box 31.

[0034] The utility model uses an exhaust fan 32 arranged on the top of the fixed frame 1 to collect debris generated during the operation of the device, thereby preventing the debris from accumulating on the base 8 or generating static electricity to be adsorbed on the surface of the calendering roller, preventing the debris from being pressed into the semi-finished product during the processing of the mask, avoiding the impact on the subsequent processing materials, and thus improving the calendering quality of the device.

[0035] When the utility model is in use, the motor 1 drives the winding roller 7 on one side to rotate. When the winding roller 7 rotates, it drives the first transmission crawler 22 at one end to rotate. When the first transmission crawler 22 rotates, it drives the first rotating shaft 23 and rotates the calendering roller on its surface. When the material passes through the first calendering roller 5 and the second calendering roller 6, it passes through the second group of calendering rollers. When the distance between the first calendering roller 5 and the second calendering roller 6 needs to be adjusted, the hydraulic lifting rod 42 in the lifting mechanism 4 is started to move the first calendering roller 5 and the second calendering roller 6. The roller 5 is raised or lowered. When the calendering roller is raised, the elastic member 27 in the first crawler 22 at the rear end contracts, so that the length of the first crawler 22 can be lengthened to prevent it from being broken. At the same time, an exhaust fan 32 is arranged at the upper end of the fixed frame 1. When the calendering device calenders the material, the exhaust fan 32 can be started to absorb and collect the debris brought out by the material. The debris enters the collection box 31 through the transmission pipe 33 and then enters the internal extraction box. When cleaning is needed, the extraction box can be pulled out to facilitate subsequent cleaning.
